A stylus pen includes a hollow pen tube, a circuit board, a pen core body, a stopping member, and a positioning assembly. The hollow pen tube extends along an axial direction and includes a pen tip end and a pen tail end. The circuit board includes a first surface and a second surface. The first surface is provided with a trigger element. The second surface faces the pen tail end. The stopping member is disposed in a pen tip chamber and adjacent to the first surface. The positioning assembly is disposed in a pen body chamber and includes a wedge-shaped fixing base and a limiting member. The wedge-shaped fixing base has an inclined surface. The limiting member is assembled on the inclined surface and abuts against the second surface, so that the first surface leans against the stopping member.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The stylus pen according to claim 1, wherein the positioning assembly comprises a positioning member, the positioning member is inserted into and assembled with the limiting member and the wedge-shaped fixing base along a radial direction, and the radial direction is perpendicular to the axial direction.
4. The stylus pen according to claim 1, wherein the limiting member has a first stopping portion, the inclined surface of the wedge-shaped fixing base has a second stopping portion, and one side of the first stopping portion adjacent to the top portion leans against the second stopping portion.
5. The stylus pen according to claim 1, wherein one side of the limiting member abutting against the second surface of the circuit board further has a notch, the second surface is provided with an electronic component, and the electronic component is received in the notch.
6. The stylus pen according to claim 1, further comprising an elongated stand, wherein the elongated stand is disposed in the hollow pen tube and extends along the axial direction, and the circuit board, at least one portion of the pen core body, the stopping member, and the positioning assembly are disposed on the elongated stand.
7. The stylus pen according to claim 6, wherein the stopping member comprises a stopping block, and the stopping block is disposed on the elongated stand.
8. The stylus pen according to claim 7, wherein the stopping member has a through hole, and the trigger element is received in the through hole.
9. The stylus pen according to claim 6, wherein the stopping member has an insertion slot, the insertion slot is on the elongated stand, and one side of the circuit board is inserted into the insertion slot, so that the first surface abuts against a slot wall of the insertion slot adjacent to the pen tip end.
11. The stylus pen according to claim 10, wherein a cushioning spring is further disposed in the hollow pen tube, and the cushioning spring abuts between the first end and the pen tip end.
12. The stylus pen according to claim 10, wherein a resilient spring is further disposed in the hollow pen tube, the resilient spring abuts between the elongated stand and the pen core body, and an elastic force of the spring is greater than an elastic force of the resilient spring.
13. The stylus pen according to claim 1, wherein the trigger element is a pressure sensing element.
